Hello, I would appreciate some help if possible. I own a nissan NV200 2013 reg. I have recently moved to France from the UK and have bought my van with me. I am in the process of registering it here but I cannot do so until it passes it's control technique. The only thing that is stopping this is the headlamp dip position and I have been told I will need to change both entire light units. Is this the case or can it be adjusted by a technician?
